    Context: The shipping industry is undergoing a transitional phase at different levels, including IMO’s e-Navigation initiative, and with this comes the need to use a human-centred design (HCD) approach to avoid accidents linked to automation issues, and to cater for the maintenance of safety and efficiency within this global transport system.Aims: The aim of this thesis is to investigate the value and challenges in HCD practice and how ergonomics/human factors (E/HF) principles can be introduced, as well as what gaps and opportunities exist in current standard operations and technologies in navigation that can potentially be followed upon by future e-Navigation developments, not only from a technological perspective but also regulatory, operational etc.Methods: This thesis derives from the work of six appended articles that mainly utilized a qualitative approach to data collections, including focus groups, interviews and observations, and to data analyses, such as narratives and a grounded theory approach. In total, two design teams and four separate sets of onboard and shore-based operators were consulted for data collection.Results: The results from the appended papers suggest that user involvement in design as well as in rule making and purchasing of new ship equipment was perceived as important for a good work environment, and efficient and safe operations onboard in this safety-critical industry. The results show that design projects are situated experiences that involve complex tasks and resource management, and that require re-iterative adaptations throughout the process. In involving the users and implementing E/HF methods, support from the management is needed and professional E/HF expertise should be a part of the team to help interpret E/HF methods and guide the process to foster continuous knowledge sharing within the team, the organization and with the users from an early stage. When investigating current operations and technologies in navigation, it was evident that gaps exist that can be improved by the redesign of current technologies or the implementation of novel e-Navigation solutions. For example, there is a large number of unintegrated systems and information sources today, and everyday routines and information across geographical areas and communication channels are not unified. Technology concepts and developments towards the e-Navigation principles have been considerably debated, yet there are still gaps that can be filled, and despite e-Navigation’s principle for HCD, the holistic – macro – perspective of the development of these new technologies seems to be under-exploited.Conclusions: Filling the existing gaps with available novel technologies is not enough to guarantee efficiency and safety in the domain, nor to guarantee acceptance. A more systemic perspective is needed, of how the different people and processes in the sea transport system can be affected by the introduction of new technology in terms of how work is performed, of regulations, new training and re-skilling, as well as of preparation for new issues that may arise with increased automation such as workload and cyber-security. This work points at the value and practice of E/HF and systems-driven design, and directs it at change makers and opinion leaders: designers, managers, rule-makers, educators, to consider the human element for safety and efficiency. In this transitional stage, one of the great values of E/HF is to more proactively prepare the shipping industry for the ongoing e-Navigation changes rather than having the industry adapt operations, regulations, training and plan the sustainability of the transport system ad hoc after technology implementation

    Currently, real-time ship manoeuvring simulations are confined to static environments e.g., desktop/full-mission bridge simulators. Seaman Online™ is a novel web-based ship manoeuvring training tool allowing students and professional mariners to practice manoeuvres in ports and confined waters from their personal computers. This paper describes the tool’s first-time implementation in a Master Mariner university programme. The students were asked to complete a post-questionnaire regarding their use experience and the results were discussed between the course instructors and the toolproviding organization at two debriefings. The aim was to obtain feedback about (a) the usefulness of the tool in manoeuvring training; (b) further design improvements and usability; and (c) how to bestincorporate it into the programme curriculum in coming academic years for improved user experience. Results revealed usability and maturity issues and the need for further guidance on simulation-based training objectives and limitations. Overall, the tool’s usefulness and potential in individual manoeuvring training were demonstrated

    A vision of Chinese MET in the 21st Century : the impact of new technology in the Chinese MET [maritime education and training]

    Get PDF
    This dissertation is a study of the new developments in maritime technology, new educational methodology and technology, and the new standards of STCW 95. The impact upon Chinese MET is analysed in relation to these three aspects. A general study is made of the latest developments in maritime technology and MET educational methodology. The outcome indicates that the influence of the integrated bridge systems (IBS) and the one man bridge operation (OMBO) have an effect on the shipping industry; the new MET educational methodology and technology also have a deep impact on the traditional way of education in Chinese MET institutions. The present status of the Chinese MET has been briefly described in order to delineate or outline the advantages and limitations of the MET. The focus is placed on instructors’ qualifications, revision of curricula and programmes, replacement of old and out of date equipment for training by new and up to date marine equipment, use of the simulator for training and assessment, and the inadequate knowledge of students in the English language communication. The results were collected and evaluated in the conclusions which highlight the necessity of adapting to technology developments. A number of recommendations are also made in view of the deep impact upon Chinese MET in the 21st century

    Journey mapping from a crew's perspective: Understanding rail experiences

    Get PDF
    Technological developments present diverse opportunities to modernise services for the rail industry. Systems can be implemented to improve passengers’ experiences, but these may also affect the experiences of crew working on board trains. This first-of-a-kind research extends the concept of customer journey mapping as a design tool to understand the experiences of train crew. To produce these crew journey maps, interviews and user observation methods were adopted (N = 22). Results show that two main negative touchpoints for the crew occur at the platform-train interface and during revenue protection activities. This paper presents an innovative methodological contribution around journey mapping to better understand rail experiences, but revolving around the crew rather than the expected consumer experience. We conclude this paper proposing requirements for technological systems and indicate opportunities for the design of systems to generate human-centred improvements for the working practices and experiences of train crew

    Automated Functions: Their Potential for Impact Upon Maritime Sociotechnical Systems

    The shipping industry is evolving towards an unknown and unpredictable future. There is speculation that in the next two decades the maritime industry will witness changes far exceeding those experienced over the past 100 years. The rapid development of artificial intelligence (AI), big data, automation and their impacts upon fully autonomous ships have the potential to transform the maritime industry. While change is inevitable in the maritime domain, automated solutions do not guarantee navigational safety, efficiency or improved seaway traffic management. Such dramatic change also calls for a more systematic approach to designing, evaluating and adopting new solutions into a system. Although intended to support operator decision-making needs and reduce operator workload, the outcomes might create unforeseen changes throughout other aspects of the maritime sociotechnical system. In the maritime industry, the human is seldom put first in technology design which paradoxically introduces human-automation challenges related to technology acceptance, use, trust, reliance and risk. The co-existence and challenges of humans and automation, as it pertains to navigation and navigational assistance, is explored throughout this licentiate.\ua0This thesis considers the Sea Traffic Management (STM) Validation Project \ua0as the context to examine low-level automation functions intended to enhance operator (both Navigators and Vessel Traffic Service Operators) navigational safety and efficiency. The STM functions are designed to improve information sharing between ships and from ship to shore such as: route sharing, enhanced monitoring, and route crosschecking. The licentiate is built on two different data collection efforts during 2017-2018 within the STM Validation project. The functions were tested on two user groups: Bridge Officers and Vessel Traffic Service Operators. All testing was completed in high-fidelity bridge simulators using traffic scenarios developed by subject matter experts.The aim of this licentiate is to study the impact of low levels of automation on operator behavior, and to explore the broader impact upon the maritime sociotechnical system. A mixed-method approach was selected to address these questions and included the following: observations, questionnaires, numerical assessment of ship behavior, and post-simulation debrief group sessions. To analyze and discuss the data, grounded theory, subject matter expert consultation, and descriptive statistics were used. The results point towards a disruption in current working practices for both ship and shore operators, and an uncertainty about the overall impact of low-level automation on operator behaviour. Using a sociotechnical systems approach, gaps have been identified related to new technology testing and implementation. These gaps relate to the overall preparedness of the shipping industry to manage the evolution towards smarter ships. The findings discussed in this licentiate aim to promote further discussions about a quickly evolving industry concerning automation integration in shipping and the potential impact on human performance in safety critical operations

    Managing Unruly Technologies in the Engine Control Room: from Problem Patching to an Architectural Thinking and Standardisation

    Get PDF
    In recent years, the work in engine control rooms (ECRs) onboard ships is becoming increasingly demanding and complex due to growing presence of modern information technology (IT) applications introduced in a problem-patching fashion. Previous studies about ECRs discussed the design issues associated with physical and cognitive ergonomics and lack of regulatory support. This paper has re-examined a design case in an ECR on a merchant ship and discussed the potential of a service-oriented architectural approach to manage emerging unruly technologies and integrate distributed resources in the maritime human-technology system. An EU project was introduced to illustrate the value of this design approach. Confronted with the complexity issues residing in a sociotechnical system like the ECR, this conceptual paper suggests a shift of focus from patching individual problems locally to a holistic systems perspective on the maritime eco-system development, which would likely require more collaborative efforts of various maritime stakeholders in practice. Certain extent of mandatory standardization for deploying and managing information systems is considered to be critical in these collaborative endeavors

    User-centered design approaches to integrating intellectual property information into early design processes with a design patent retrieval application

    Get PDF
    The relationship between intellectual property rights (IPRs) and the development of creativity is always a controversial topic. However, it has seldom been explored from the user-centered design (UCD) perspective. This paper describes how the UCD approach has been employed to develop Design Patent Retrieval Application (acronym: DsPLAi), a mobile app aimed to integrate IPRs related information into early design processes to enhance designers’ IP practice and to facilitate the creative process. Interview studies were first conducted to identify end-users’ understanding of IPRs and related practices. Next, participatory design workshops with designers and IP processionals were organized to understand the interaction between the two parties and their needs, thereby deriving requirements for DsPLAi. A prototype of the app was developed and evaluated with ten industrial designers. The prototype received positive feedback in the usability evaluation. The empirical results showed that the provision of IPRs related information at an early stage could be helpful to the design process and that the designers were positive about the use of DsPLAi in their daily design routines

    Strategies and Measures to Improve the Work Environment of Service Crew on Board Swedish Passenger Vessels

    Get PDF
    This paper presents findings from three workshops focused on the physical, organizational and social work environment of service crew working on board Swedish passenger vessels. The first workshop aimed to identify underlying causes of long-term sick leave among employees in the service department, and potential measures that can be taken to reduce ill-health. The second and third workshop explored knowledge of available methods to identify occupational safety and health risks, and suggest health-promotion strategies at individual, team and company levels. A total of 58 persons from the Swedish maritime cluster participated in the workshops. During the workshops, open and structured brainstorming was used to create affinity diagrams to systematically summarize the identified causes, risks and strategies. Although the results presented in this article stem from a research project focused on Swedish passenger vessels, many of the findings may be transferable to an international maritime setting towards a deeper understanding of seafarers’ work environment and working conditions
